It’s just as important and beneficial (if not more so) to focus on diet quality rather than quantity, says a 2018 study published in the Journal of the American Medical Association. Focus on real foods rather than a strict number of calories and you’re more likely to stay slim over the long term. Shapiro recommends these shedding superfoods, in particular:
High-intensity interval training (or HIIT) boosts your metabolism, burns calories, and builds muscle: a triple threat belly fat cannot reckon with. “High-intensity interval training is when you perform an exercise at or close to your maximum ability for a short period of time and then take a brief respite and do it again. HIIT should usually be done on a 2:1 interval, meaning if you did an exercise for one minute, you rest for 30 seconds and then repeat,” explains Dr. Alex Tauberg, DC, CSCS, EMR. “This can be a great way to flatten that stomach when you don’t have too much time to work out.”
So how does this work? A quick run-through: The first tip was to eat low carb. This is because a low-carb diet lowers your levels of the fat-storing hormone insulin, allowing your fat deposits to shrink and release their stored energy. This tends to cause you to want to consume fewer calories than you expend – without hunger – and lose weight. Several of the tips mentioned above are about fine-tuning your diet to better this effect.
And maybe a new mattress, because it’s not just the amount of time you spend sleeping that keeps you lean, it’s also the quality of your sleep. Fat cells in your body produce a hormone called leptin that helps the body keep track of how much potential energy (i.e. fat) it has stored. But leptin is only produced during certain stages of sleep. Miss out on those stages because you’re not resting soundly enough, and you’ll disturb levels of the hormone, leaving your body with no real idea of its energy reserves. Consequently, you’ll end up storing calories rather than burning them.

That’s because it theoretically causes a mild ketosis (yep, the basis of the keto diet), which is a fat-burning state that should make you feel less hungry. The key in being successful with a low-carb diet (especially if you’re used to a more high-carb lifestyle) is to compensate for those lost carbs with protein-rich foods, says Dr. Cheskin. That way, your volume of food stays the same, but you’re doing it healthfully rather than in a way that exacerbates your weight gain.

The meals shown here are "templates" that you can vary any number of ways to please your tastebuds and avoid eating the same old thing every day. Follow them and you'll get between 2,400 and 2,800 calories per day. That should provide plenty of calories for all but the most severely obese, while allowing most guys to lose fat around their middles at a steady pace. (Don't worry about hitting the numbers on the nose every time. If you exceed your fat quota during lunch, for instance, just cut back a little during dinner.)
Every so often we find that there is something that is not pushing us enough for us to achieve that which we would like to. The cause for this is not in your efforts may be, it could lie with your mind. There is a great chance that you are not entirely motivated to lose weight in 10 days. If you think that you are lost and have no hope to get going then here is some motivational ideas that may help you. For starters, stand in front of your mirror and ask yourself if you like the person you are staring at before you start asking how to lose weight in 10 days. https://www.youtube.com/watch?v=cIWBSfa-FLA
